Objects of the invention reside in the provision of a novel, rugged and attractive toy of the bouncing hobbyhorse type, which is constructed mainly of flat bar metal stock, such as spring steel, which is able to accommodate and to function satisfactorily with riders of widely differing weights, and which provides a securing structure for adequately securing the spring bar, seat and head piece of the device together while permitting the head piece to be constructed of relatively thin wood or the like without liability of the head piece breaking.

The invention will be better understood by reference to the vaccompanying drawing forming a part hereof and in which- Figure 1 is a perspective View of a toy embodying my invention;

Figure 2 is a partial section substantially on the line 2--2 of Figure 1;

Figure 3 is a partial sectional view substantially on the line 3-3 of Figure 1;

Figure 4 is a partial sectional view substantially on the line 4-4 of Figure 1; and

Figure 5 is a section substantially on the line 5-5 of Figure 1.

Referring to the drawing, two base members of ilat metal stock, preferably spring stock, are respectively designated at I and 2. These have their widths disposed vertically, and bolts 3 pass through registering apertures, respectively designated at 4 and 5, through the base members, as best shown in Figure 4, and secure the same together forwardly in face-to-face and correspondingly lineally extending relation, These base members are oppositely curved lineally and n facewise and away from each other, as respectively designated at 6 and 'l in Figure 1, rearwardly from the region 8 at which they are secured together by the volts 3 whereby they diverge horizontally from the region 8 to form the base of the device.

The base member 2 terminates immediately forward of the region B, and the base member I extends and is twisted forwardly of the region 8, as designated at 5 and best shown in Figure 4, to dispose the width of its forward portion horizontally as designated at I0. This forward portion is curved lineally and facewise thereof upwardly into a part coil Il.

A spring bar I2 of iiat metal spring stock, see Figure 1, has its width disposed horizontally and has its forward end portion curved lineally and facewise thereof and downwardly therefrom into the form of a coil I3 engaging underneath the adjoining portion of the spring bar as designated at I4. The spring bar coil I3 is seated in the part coil I I of the base with the spring bar l2 extending from the top of the spring bar coil upwardly and rearwardly over the base. A boit i5, passing through registering apertures, respectively designated at I5 and Il in Figure 5, through the part coil II and spring bar coil I3 in the region of the extending end of the part coil II, secures the spring bar coil in the part coil with the spring bar extending upwardly and rearwardly over the base as aforesaid.

A flat seat IB of thin Wood or like material is arranged in the region of the rear end of the spring bar I2 and has a fiat longitudinal extension I9 extending longitudinally of and overlying thespring bar in face-to-face relation therewith. See Figures 1 and 2. A at head piece 29, shown in the form of a horses head, is arranged above the seat extension I9 and has its plane disposed normal to the planes of and longitudinally of the extension and spring bar and has its lower edge engaging downwardly on the extension. As so arranged, the spring bar, seat extension and head piece are secured together by means of duplicate bolt structures spaced longitudinally of the extension and spring bar, one of these bolt structures being described below with particular reference to Figure 2.

A headed screw 2l extends upwardly through registering bores, respectively designated at 22, 23 and 24, through the spring bar i2, the seat extension I9 and in the head piece 2U, of which the bore 24 of the head piece is disposed parallel to the -faces thereof, and a nut 25 is threadly engaged by the screw 2l and is disposed in an aperture 26 extending facewise through the head piece and intersecting the bore 24 of the head piece. Thus is provided securing means for adequately securing the spring bar, the seat extension and the head piece together in their aforesaid relation which is not liable to cause breakage of the relatively thin head piece.

A transverse handle bar 2 is mounted upwardly on the head piece 2E! to be grasped by a child seated on the seat i8, and a foot bar 2S is adjustably secured on the intermediate portion of the spring bar, see Figures 1 and 3, by means of a U-shaped clamp member 29 embracing the spring bar and passing through the foot bar, and thumb screws 30 screwthreaded on the legs of the clamp member to clamp the foot bar on the spring bar.

A child, seated on the seat I8 and grasping the handle bar 2'.' and having his feet resting on the foot bar 28 may bounce by reason of the resiliennated at 3l, to permit freedom of action of they part coil and spring bar coil, the spring bar coil resting on the part coil at the bottoilltherof. The spring bar I2 tends to wrap aboutthespring bar coil I3, the spring bar coil tends to" expand horizontally and to contract yertically,..and the part coil I I tends to decrease its radius as weight is applied on the seatwwith the result'that the device is able to accommodate and function satisffactorily with a wide'range of weights on'theseat. .While I have thus described my invention, Il do not wish to be limitedto vthe precisdetails described`,`as changes may be readily `made 4without departing from"'the spirit of'rny invention, but
